This article delves into the ongoing debate surrounding the role of age in second language acquisition, examining developments over the past three decades and highlighting contentious issues. We argue that the commonly held belief in age's pivotal role is frequently contradicted by empirical evidence. Additionally, we examine the agerelated debate…

A fundamental distinction in the field of second language acquisition (SLA) is route versus rate of acquisition (or L2 development). While the former has traditionally referred to developmental sequences of learning, the latter denotes the speed with which learners progress through developmental trajectories (Muñoz, 2006). A second distinction at…

Background: Spelling acquisition requires the assimilation of the regularities of the writing system, but these regularities may differ between the native and a foreign language. English spelling acquisition is a challenge for Spanish-speaking children due to differences in the orthographic systems. The aim of this study was to examine to what…

The role of parental literacy skills in cross-linguistic transfer, the phenomenon of the sharing of skills and competence from one language to another, is under-researched. The present study tested 147 Hong Kong Chinese children and their parents (76 boys; mean age = 7.16). Parental literacy skills significantly explained children's reading and…

This study compares the achievement of two cohorts of immigrants with ages between 7 and 30 years old. Two sets of participants were assessed in two points in time and in different regions of Portugal. 169 students with similar immigration conditions for this analysis (nationality, length of residence, previous education in the country of origin)…

The effect of language aptitude on grammar attainment of second language learners with different ages of onset became one of the hot topics in the last decades. However, most previous studies were conducted in a second language context with inconsistent results, and few studies were conducted in a foreign language context. To fill this gap, the…

Among the existing sign language assessment tools, only a small number can be used in clinical settings. This contribution aims at presenting three comprehension assessment tests (two lexical and one syntactic) that offer a solid basis to build tools to assess language impairments in deaf signing adults. We provide the material and guidelines,…

Recent evidence suggests that deaf children with CIs exposed to nonnative sign language from hearing parents can attain age-appropriate vocabularies in both sign and spoken language. It remains to be explored whether deaf children with CIs who are exposed to early nonnative sign language, but only up to implantation, also benefit from this input…

This study examines the reflexivity of immigrant children in forming their language attitudes (LAs). Considering the special cultural environment of the Chinese community in Australia, which refers to the community's well-matched cultural powers with Australia, this research explored Chinese Australian children's conflicting but reflexive LAs and…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

Late exposure to the first language, as in the case of deaf children with hearing parents, hinders the production of linguistic expressions, even in adulthood. Less is known about the development of language soon after language exposure and if late exposure hinders all domains of language in children and adults. We compared late signing adults and…

Montrul's (2008) onset age hypothesis predicts that, if attrition occurs in early bilingualism, it will be more severe in simultaneous than in sequential bilinguals. This study tested that prediction in an eye-tracking experiment focused on the processing of Spanish gender agreement during sentence reading. Heritage Spanish speakers exposed to…

This paper sets out to peruse the role of various theories or more precisely, hypotheses invoked in second language acquisition (SLA) research by surveying three empirical studies pertaining to the critical period hypothesis in the SLA of phonetics and phonology. In particular, the three studies reviewed are titled in chronological order as (1)…

Purpose: This study aimed to investigate the intelligibility of children's atypical speech in relation to listeners' language background. Method: Forty-eight participants listened to and transcribed isolated words repeated by children with speech sound disorders. Participants were divided into, on the one hand, a multilingual group (n = 29) that…

Children with autism often display discrepancies in their intellectual functioning, with nonverbal skills frequently being more developed than verbal. Compared to monolingual autistic children, however, much less is known about how bilingualism affects intelligence in autism. The current study examined the intelligence profiles of 146 bilingual…
